Sexual desire, frequency of coitus, frequency of orgasm, which partner took the first sexual initiative, and the level of sexual satisfaction were studied in 205 women in puerperium in relation to age in the year preceding pregnancy and during pregnancy. It seems evident that sexual desire and the frequency of coitus and orgasm diminish during pregnancy independently of age. The group of younger women (16 to 20 years old) in our study maintained a relatively higher level of sexual activity especially in comparison to older women (36 to 40 years old). The number of women who took the first sexual initiative increased considerably in pregnancy.
